All of these weapons have infinite ammo, the unlockable Combat Knife never breaks, and it can be used to counterattack an enemy, but if done so it will be lost if the player doesn't collect it back by killing the enemy and examining its corpse.

All ∞ Bonus Weapons will be unlocked at once if the "All In-game Rewards Unlock" DLC is bought.

Once unlocked, these weapons will be in the Item Box for both characters in every difficulty.
